uCos中間件－ZLG/FS（版本1.0），碰到問題了！請版主提示！ |
| 作者：risun007 欄目：ARM技術(shù) |
在2132的開發(fā)板上，通過跳線連接SD卡。sdconfig.h里管腳已經(jīng)配置正確，并確認(rèn)讀寫沒有任何問題。但用uCos中間件－ZLG/FS（版本1.0）的演示程序，寫一個字符串到文件“a：\\單片機(jī).txt”一直沒有成功。SD卡塊地址0的數(shù)據(jù)讀出來了。根據(jù)第一頁數(shù)據(jù)以下得出得數(shù)據(jù)都是0，這感覺就不對了。 /* 每扇區(qū)字節(jié)數(shù) */ DiskInfo[i].BytsPerSec = Buf[11] | (Buf[12] << 8); //（＝0） /* 每簇扇區(qū)數(shù) */ DiskInfo[i].SecPerClus = Buf[13];//（＝0） /* FAT開始扇區(qū)號 */ DiskInfo[i].FATStartSec = Buf[14] | (Buf[15] << 8);//（＝0） /* FAT表個數(shù) */ DiskInfo[i].NumFATs = Buf[16];//（＝0） /* 根目錄占扇區(qū)數(shù) */ 請指點(diǎn)一下，是不是還有什么地方我沒有注意到得。 塊地址0數(shù)據(jù) E9 FD FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 00 05 00 00 00 01 00 00 00 FF C9 03 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 55 AA |
